MOP.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed July 23, 1915. Serial N 0. 41,506.

1/ 0 all whom it may concern.

Be it known that I, WILLIE H. GRUEN- I-IAGEN, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Mops, of which the following is a specification.

My invention relates to mops and has for its object to provide an endless-band mop of fabric material in combination with a mop holder which receives said band between a pair of rollers, together with means for turning said rollers so as to run the endless band of fabric material between the rollers for wringing the water from the mop.

It is an especial object of my invention to provide a. combination as above outlined in which it will be practicable readily to remove the endless-band mopping fabric from between the rollers for replacing the same, washing or for other purposes.

It is also an object of my invention to provide means for attaching a brush to the mop holder in such manner that the brush may be operated upon the floor in place of the mopping fabric.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustrating the application of my invention in one form,Figure 1 is a plan View of my improved interchange mop and scrub-brush with the brush attached and with a portion of the mop band cut away to show parts beneath. Fig. 2 is a side elevational view of the parts shown in Fig. 1 with a portion of the frame removed showing the application of the mop in a forward stroke. Fig. 3 is a sectional side elevational View of the parts shown in Fig. 2

illustrating the application of the mop in a backward stroke. Fig. 1 is a view of the mop similar to Fig. 2, but taken from the other side, with the scrub-brush attached, showing the application of the scrub-brush.

.Fig. 5 is a front sectional view on line 5-5 of Fig. 1 showing'the method of attaching the scrub-brush. Fig. 6 is a side elevational view of the same side of the mop shown in Fig. 4, illustrating the position of the mop when the mop band is being wrung. Fig. 7 is a bottom view of the mop showing the wringer roller partly removed. Fig. 8 is a plan view of a part of the mop with parts removed and others opened to allow of the complete removal of the mop band.

The frame of my mop comprises three members 10, 11 and 12 made of strap metal rigidly riveted together at the rear by rivets 1 1 of which members 10 and 11 are so bent as to form wings 15 and 16, which in turn are riveted to a rectangular portion 17 of a handle 18 by rivets 19. Frame members 10 and 11 are also bent to provide side portions 20 and 21. Frame member 12 is similarly bent to form side portions 22 and 23 which are spaced some distance from the side portions 20 and 21 of frame members 10 and 11 but which further on meet said side portions 20 and 21 at 24 and 25 and are riveted to them with rivets 26. Portions 24 and 25 form the front portions 30 and 31, meeting at 27, and are joined by means of the countersunk stove bolt 28.

The mop band 29 of my invention consists of a piece of coarse thick fabric sewed together at the ends to form an even continuous belt. It passes between two corrugated rollers 32 and 33 and around the front portions 31 and 32 of frame member 12. When the mop is given a forward stroke mop band 29 takes the position shown in Fig. 2, and when the mop is given a backward stroke mop band 29 takes the position shown in Fig. 3.

The brush 34 is supplied with spring clips 35 screwed to the top of said brush and adapted to engage with the frame of my invention, as best shown in Fig. 5, for the purpose previously set forth. Spring clips comprise a horizontal portion 36 bywhlch they are secured to the brush 34, a curved portion 37 to allow suitable spring action, a vertical portion 38 to engage with the edges of slots 39 to prevent forward or backward motion relative to the frame, a horizontal portion 40 to engage with the tops of the frame-member portions 2025 and 21-21to maintain the brush in place, and lastly a recedingportion 41 for spreading and directing said clips when the brush is inserted. It is quite evident from the drawings that the brush is attached by merely pushing it in place, the clips 35 directing and holding it in the proper position. The application of the brush is shown in Fig. 4, the mop band 29 is thrown back, leaving the brush in free contact with the surface to be cleaned. When the brush is de- Zia sired to be removed the portions 41 of the clips are spread out and the brush can be withdrawn. v

The corrugated rollers 32 and 33 are provided with axial rods 42 and 43 which rotate in elongated circular slots 44 45, 46 and 47 in the portions 22 and 23 of frame member 12. Rod 42 extends on both ends beyond frame portions 22 and 23 up to the inner surface of frame portions 20 and 21. Rod 43 terminates on one end immediately beyond frame portion 22 and extends on the other end through the circular slot 47 in frame portion 23 and through a similar slot 53 in frame portion 21. Outside of the frame rod 43 takes the form of a hand crank 48, which is so shaped that the extremity of the handle 149 comes exactly level with the crank portion 48 and clears all portions of the mop when said crank is rotated. When the mop band 29 is to be wrung the whole mop is inverted and held by the portion 17 of the handle 18 in a position clearly shown in Fig. 6. A. water table 49, having a beveled edge 50 is riveted to the frame member 12 by rivets 51, as clearly shown in Fig. 1, and serves to remove all water on the surface of the mop band 29 when the same is being wrung. Rollers 32 and 33 are kept in gripping contact with the mop band 29 by means of the corrugations on said rollers and by means of a pair of tension springs 154 and 52 which loop over the protruding ends of rod 42 and are attached to the upper portions of the water table 49, as best shown in Figs. 1 and 2. When the mop band 29 is sufficiently dry the Wringer crank 48 and handle 149 are left in a position shown in Figs. 1 and 4, where the same are out of the way.

In time the hoop band '29 will wear out and must necessarily be replaced by a new one, or for other reasons it may be desirable to remove the band. Since mop band 29 is continuous, surrounding roller 33 and frameportion 31, to remove same this roller must be segregated from the frame and an opening in the frame must be provided through which the mop band can be withdrawn or inserted. This is done as follows. Slots 47 and 53 are provided with openings or outlets 54 and 55 through which the crank end of rod 43 can be removed. To change mop bands handle 149 is drawn back, as shown in Fig. 7, drawing back roller 32 at the same time. The crank end'of rod 43 can in this position be withdrawn from the frame members 23 and 21 through the openings 54 and 55, and when withdrawn sufliciently'to permit the roller 33 to clear the frame said roller 'can be directly pulled out from the frame and mop band 29, leaving mop band 29 surrounding only frame portion 31. The joint in frame comes requisite in such an assemblage that the parts fit loosely enough so that the above-named operations place. It will be noted that roller 32 is not removed at all while shifting the mop bands, and that the'spr-ings 51 and 52 which hold it in place do not interfere with any movement whatsoever of the rod 43 of roller 33. Slot 44, as seen in Fig. 2, is provided with an o ening 56 similar to the openings opening are assembled,
